[分享]FRED如何调用Matlab [复制链接]

简介：FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图，本文的目的是通过运行一个案例来实现与Matlab的相互调用，在此我们需要借助脚本来完成，此脚本为视为通用型脚本。 -Mx\W|YK  
BfOQ/k))  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： Z36C7 kw  
enableservice('AutomationServer', true) uS}qy-8J  
enableservice('AutomationServer') \!Cc[n(f#  
/t"FZ#  
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 glo Y@k~

在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： m?)REE  
1. 在FRED脚本编辑界面找到参考. }XcYIo#+t  
2. 找到Matlab Automation Server Type Library gR\-%<42  
3. 将名字改为MLAPP mA2L~=v#

在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix，PutWorkspaceData适用于存储一般的数据在工作区，并赋予其为变量，PutFullMatrix试用于复数数据。 RF$2p4=[

现在将脚本代码公布如下，此脚本执行如下几个步骤： (RBzpAiH  
1. 创建Matlab服务器。 x4=Sm0Ro|V  
2. 移动探测面对于前一聚焦面的位置。 lo< t5~GQ  
3. 在探测面追迹光线 PqDff

4. 在探测面计算照度 ;%W]b  
5. 使用PutWorkspaceData发送照度数据到Matlab RM|2PG1m  
6. 使用PutFullMatrix发送标量场数据到Matlab中 P#o"T4 >  
7. 用Matlab画出照度数据 ewrs D'?  
8. 在Matlab计算照度平均值 ta+MH

9. 返回数据到FRED中 F :p9y_W
